sysinstall

一直有人抱怨FreeBSD的bsdlabel(8)和fdisk(8)不好用，而进一遍sysinstall又太过麻烦，因此这次有人把磁盘编辑器从sysinstall(8)里面拆了出来，作了一些修改使其成为了一个新的工具——sade(8)。

About 9 Years ago, FreeBSD has introduced a functionality in sysinstall(8)’s partition editor, which is to mark a partition “active”.

However, unfortunatelly, the implementation contained a flow from the day 0 it was introduced. Sysinstall(8) depends on user’s sanity not to mark only one partition as active on one disk.

This turned out to a potential damage of disk partition table. With two partitions marked “ACTIVE”, you will get the following message:

“Invalid partition table.”

Then system will halt.
